This includes 27 files ( 1x .c4d / 13x .stl / 13x .obj ) to both print and create your own heavy-duty handle. There are 7 handle models ready-to-print in both stl and obj formats. To create your own insert, open the c4d file or just import the non-threaded handle file into your desired CAD program. Then use the boolean files or any file of your choice to cut out the insert shape. Threads have been oversized by 22% to account for PLA shrinkage after printing.
NOMINAL HANDLE SIZE IS 1x 1 x 4", ENSURE THAT YOUR PRINTING SLICER IS TO CORRECT SCALE/UNITS BEFORE PRINTING
